BINGO5 ORACLE

BINGO5 ORACLE is an entertainment app for Japan's BINGO5 lottery (issued by Mizuho Bank). It pulls the full draw history from the internet and combines proprietary statistics with Claude AI commentary to suggest five sets of numbers per tap.

The 3 × 3 grid has FREE at the centre and eight surrounding cells, each with its own fixed five-number range (A1 = 1–5, A2 = 6–10, …, C3 = 36–40). BINGO5 ORACLE analyses the appearance trends per cell.

Five strategies:
- Hot: prefers numbers that appear often
- Cold: prefers numbers that have been absent
- Pure Random: completely uniform random pick
- Even-Odd Split: constrains the eight numbers to a 4:4 even-odd ratio
- Secret Algorithm: a confidential per-cell blend of top frequency / low frequency / longest gap / cycle detection (in-app purchase to unlock)

Statistics tab:
- Per-cell histogram over the five candidates
- HOT / COLD TOP3 per cell with slot display
- Loaded draw count and theoretical rate (1/5 = 20%)

Data fetching:
- Pulls the full history at launch
- Choose "Last 100", "Last 500", "All", or a custom count (5–3000)
- Falls back to a 40-draw offline sample bundled with the app
